SUBWOOFER (supplied with MX packages only)
• Install the subwoofer wherever you like because with the
bass sound range reproduced from the subwoofer (below
150Hz) human hearing cannot detect the direction and
position where the sound is being produced.
• Also, since the feeling of stereo is lost with bass
frequencies, a single subwoofer is enough for reproducing
the bass of stereo channels.
• To obtain a better bass reproduction, we recommend that
you place the subwoofer on a solid floor where resonance
is unlikely to occur.
• Always place the subwoofer vertically, keeping a few
centimeters away from the wall.
• Do not place any object on the subwoofer or sit on it.
• If the subwoofer is placed in the center of a room, the bass
could be extremely weakened. This is due to the influence
of the standing wave of the room. If this happens, move the
subwoofer away from the center of the room or eliminate
the cause of the standing wave by installing a bookshelf on
the wall, etc.
Important!
Before you operate the subwoofer, complete the preparation
procedures. Switch on your receiver and select the sound
source.
The type plate is located on the rear of the subwoofer.
1 Use the cinch cable supplied to connect AUDIO IN to
SUBWOOFER PRE-OUT at the receiver.
2 Check whether the power voltage as shown on the type
plate corresponds to your local power voltage. If it does
not, consult your dealer or service organization.
3 After all connections have been made, connect the
AC power cord to the receiver or the wall outlet.
To disconnect the subwoofer from the power completely,
remove the power plug from the wall outlet.
• Rotate VOLUME clockwise until there is a click.
y The LED indicator lights up in green.
• Rotate VOLUME anticlockwise until there is a click.
y The LED indicator light turns red.
You can adjust the subwoofer to suit the sound level of your
front speakers. Reinforcing the bass sound gives you a
greater sense of atmosphere.
1 Adjust the VOLUME on the receiver until the sound from
the front speakers is not distorted. If it is distorted, the
sound from the subwoofer will also be distorted.
2 Play your favourite songs. Male vocal tunes containing bass
sounds are most suitable for adjustment.
3 Adjust the VOLUME on the subwoofer to determine the
loudness of the bass sound from the subwoofer.
• Use PHASE SELECTOR located
at the rear of the subwoofer to
select the phase polarity.
Selecting the polarity at either 0° or 180° may determine
better bass reproduction effect in certain listening
environments (depending on the type of front speakers and the
position of the subwoofer). It may also change the expanse
and tightness of sound, and affect the feeling of sound field.
• Select the setting that provides the sound you prefer when
listening in your usual listening position. Repeat the
adjustment for volume and phase polarity to suit your
preference.
Once you have adjusted the subwoofer to the settings you
desire, use the VOLUME control on the receiver to adjust the
volume of the subwoofer and the other speakers. You do not
need to adjust the subwoofer settings again even when you
change the volume level of the receiver.
